| pubmed-article:425540 | pubmed:abstractText | In a prospective study 73 patients on maintenance digitalis treatment at the Paracelsus Institute, Bad Hall, were clinically examined and the dosage of the drug was adjusted according to cardiac symptoms. The clinical effects were correlated to digoxin concentrations measured on the day following admission to hospital and on the 21st day of treatment. The following practical conclusions were reached: 1. More than 50% of the patients were underdigitalized. 2. There is often no indication for digitalis therapy in patients with a low daily maintenance digoxin dosage and normal renal funciton. 3. The usual recommended maintenance dosage of digoxin provides serum digoxin levels in the lower region of the therapeutic range. 4. Patients with symptoms of decompensation taking an average dosage of digoxin need more digitalis. There is generally no danger of toxicity when the dosage is increased. 5. The serum digoxin concentration in patients with slightly reduced renal function lies in the upper region of the therapeutic range with usual doses of digoxin. | lld:pubmed |
